Cement finishing attachment for cement rake

ABSTRACT

A cement finishing attachment for a cement rake includes a cement finishing blade with a first face, a second face, a first edge, a second edge and peripheral side edges. At least one retainer is positioned on the second face of the cement finishing blade for fixing the cement finishing blade to a rake blade of a cement rake and a receiver is positioned on the second face of the cement finishing blade for receiving a shaft of the cement rake.

FIELD

There is described a cement finishing attachment for use with a cementrake.

BACKGROUND

When finishing cement, a large bull float is often used to level andsmooth the surface. There are certain areas in which the bull floats donot fit or are awkward to use such as under stairs or in tight areas.

SUMMARY

There is provided a cement finishing attachment for a cement rake. Theattachment has a cement finishing blade with a first face, a secondface, a first edge, a second edge and peripheral side edges. At leastone retainer is provided on the second face of the cement finishingblade for fixing the cement finishing blade to a rake blade of a cementrake. A receiver is positioned on the second face of the cementfinishing blade for receiving a shaft of the cement rake.

The position of the retainers on the cement finishing blade may differbased upon the style of cement rake being used. If the shaft of thecement rake is positioned in a central location near or at an edge ofthe rake blade then the retainers may be positioned at the second edgeof the cement finishing blade. The position of the receiver is alsodependent upon the style of cement rake being used. If the shaft of thecement rake is positioned in a central location near or at an edge ofthe rake blade then the receiver may be positioned at the center of thecement finishing blade.

Although a single retainer may be used to connect the cement finishingblade to the rake blade, it is preferable that two retainers be used.The two retainers are preferably positioned near each peripheral sideedge to provide greater stability and limit movement of the cementfinishing blade when attached to the rake blade.

A shaft support may be positioned on the second face of the cementfinishing blade for engaging the shaft of the cement rake. Preferablythe shaft support is positioned at the first edge of the cementfinishing blade. Shaft support may have a concave surface that helps tomaintain position and stability of the cement finishing blade whenengaged with the shaft of the cement rake.

Although the length of the cement finishing blade may be of any length,it is preferable that the cement finishing blade be the same length asor longer than the rake blade to which it is attached.

DETAILED DESCRIPTION

A cement finishing attachment for a cement rake generally identified byreference numeral 10, will now be described with reference to FIGS. 1through 6.

Structure and Relationship of Parts:

Referring to FIG. 1, a cement finishing attachment 10 has a cementfinishing blade 12 that has a first face 11, a second face 13, a firstedge 14, a second edge 16 and peripheral side edges 18. Retainers 20 arepositioned on second face 13 of cement finishing blade 12. In theembodiment shown, there are two retainers 20 that are positioned atsecond edge 16 of cement finishing blade 12; however, it will beunderstood that a single retainer 20 or several retainers 20 may beused. The two retainers 20 are preferably positioned near eachperipheral side edge 18 to provide greater stability and limit movementof the cement finishing blade 12 when attached to the rake blade 32.Referring to FIG. 5 and FIG. 6, retainers 20 fix cement finishing blade12 to a rake blade 32 of a cement rake 30. Referring to FIG. 1, areceiver 22 is positioned on second face 13 of cement finishing blade12. Receiver 22 is preferably positioned at the center of cementfinishing blade 12. Referring to FIG. 5 and FIG. 6, receiver 22 receivesthe shaft 34 of cement rake 30. A shaft support 24 is positioned onsecond face 13 at first edge 14 of cement finishing blade 12 whichengages shaft 34 of cement rake 30 and helps to maintain position andstability of cement finishing blade 12 when engaged with shaft 34.Referring to FIG. 2, shaft support 24 has a concave surface 25 whichcradles shaft 34 of the cement rake.

Referring to FIG. 3 and FIG. 4, in the embodiment shown, receiver 22 ismade up of two portions, a fixed portion 26 and a removable portion 28.The two portions are connected together by a pin 29. It will beunderstood that different types of receivers 22 may be used, including afriction connection or clip.

Cement finishing blade 12 is preferably the same length as or longerthan rake blade 32; however, it will be understood that a cementfinishing blade 12 with a shorter length than rake blade 32 may also beused.

Operation:

Referring to FIG. 4, cement rake 30 and cement finishing attachment 10are separate from each other with removable portion 28 of retainer 22separated from fixed portion 26. Referring to FIG. 6, retainer 20 isslid onto rake blade 32 and shaft 34 is positioned within fixed portion26 of receiver 22 with shaft support 24 receiving shaft 34. Removableportion 28 of receiver 22 is slid into place and pin 29 is used to holdfixed portion 26 and removable portion 28 of receiver 22 together.

Once cement finishing attachment 10 has been connected to cement rake30, the cement rake 30 may be used during the levelling and smoothing ofa cement pad and then rotated to allow first face 11 of cement finishingblade 12 to be used for levelling and smoothing
